Guess I should look at more than just one service guide. I think I saw that the readings were taken with a 20,000 ohm/volt on the Sams, but I will double check tonight. The info on the Riders version is much more in line with the results I was getting. Thanks for pointing that out. I am currently using an Ideal 61-766 meter that I would like to replace, as I do not need the clamp portion of it and it makes it difficult to set on the bench and remain viewable.
I am still having problems with volume with the radio playing, the record changer sounds wonderful and can get very loud. I have to have the volume pretty much maxed to hear radio stations. There are still higher than normal voltages on both pin 3s of the 7H7 tubes. There is a 33k resistor and 240 pf capacitor leading to pin 3 of the 7F8 left to replace in that circuit, but they are under the band switch assembly.
7H7 1st IF Amp
pin 3 = 173v (105v expected)
7H7 2nd IF Amp
pin 3 = 148v (125v expected)
I will double check the pin 4 voltages on both 6V6's also.
